I haven't heard of it, but I know there are issues with ultrasonic=20
radiation - don't want to get too much.  also, look into how much energy =

is involved to generate and focus ultrasound.  there are lots of ways to =

put too much energy into the process and get a negative return (kinda=20
like corn ethanol!).

I've noticed some web sites that are touting using
ultrasound to mix biodiesel. Does anyone know if this
is legit or just some biodiesel scam? Seems like the
sound waves could be the ultimate mixer but could also
just the usual internet scam.

  Alfred L. Loomis noticed the first chemical effects of ultrasound in =
1927,
but the field of sonochemistry lay fallow for nearly 60 years. The
renaissance of sonochemistry occurred in the 1980's, soon after the =
advent
of inexpensive and reliable laboratory generators of high-intensity
ultrasound.
